How to Create a Topical Map for SEO, Step by Step

What a topical map contains: entities, subtopics and questions

A keyword list tells you what people type. A topical map goes further and shows how those searches fit into a subject. It is usually a spreadsheet or a diagram, and it turns scattered keyword ideas into a site structure.

• Seed topic: the central subject, such as home composting.
• Entities: the things the topic involves, such as compost bins, earthworms, nitrogen, carbon, kitchen waste and leaf mould. Covering these helps search engines connect your pages to the subject, as explained in the semantic SEO guide.
• Subtopics: meaningful parts of the topic, such as methods, materials, problems and using finished compost.
• Questions: the specific things people ask, such as "why does my compost smell" or "can I compost citrus peel".
• Intent: whether each search wants to learn, compare, buy or find a place.
• Hierarchy and links: which page is the parent, which pages sit under it, and which pages should link to each other.

How a topical map guides content and site structure

The map works as a blueprint. The top level becomes a hub or pillar page, the subtopics become sections or category pages, and the questions become individual articles or sections within articles. Because every planned page has a parent and siblings, the internal linking plan comes from the map rather than being added as an afterthought.

A map also prevents two common problems. It stops you writing two pages that target the same search, and it shows which important subtopics have no page at all. That makes it the foundation for building authority on a subject over time.

Building a topical map step by step

1. Choose the seed topic. Pick a subject that matches your audience and what you can genuinely teach, such as home composting for a gardening supplies shop.
2. List the entities. Write down the people, objects, materials and processes involved. Encyclopaedia entries, product manuals and textbooks are good starting points.
3. Gather queries. Use keyword research tools to collect searches around the seed and each entity.
4. Mine People Also Ask and autocomplete. Type the seed and its subtopics into Google and record the suggested searches and the questions that appear in People Also Ask boxes.
5. Study competitors. Look at how two or three sites that rank well organise the topic: their categories, headings and the questions they answer.
6. Label intent. Mark each query as informational, commercial, transactional or local, using the patterns in the search intent guide.
7. Group into pages. Combine queries that the same page can answer. Clustering by SERP overlap makes these decisions more reliable.
8. Build the hierarchy. Arrange the pages under a pillar and a few subtopic groups, no more than two or three levels deep.
9. Plan the links. For each page, list the parent it links up to, the siblings it links across to and the anchor text to use.

Example topical map: home composting

Below is a simplified map for a gardening site. A real map would have more rows, but the structure stays the same.

Notice that the entities from step two appear across the map: earthworms in vermicomposting, carbon and nitrogen in the greens and browns article, kitchen waste in the Bokashi page. Spreading entities this way means each page covers its own angle in depth while the section as a whole covers the subject, and the "Links to" column shows exactly where readers can go next.

Prioritising which pages to create first

A full map can hold dozens of pages, so decide the order deliberately rather than writing from the top down.

• Publish the pillar and the subtopic pages early, because they give every later article a place to link to.
• Bring forward pages close to your business goals, such as the bins and equipment page for a shop that sells bins.
• Favour questions that real customers ask you, since you can answer them with first-hand detail.
• Check Search Console for queries where you already get impressions without a dedicated page; these are quick wins.
• Leave narrow, low-demand questions for later or answer them as sections inside a broader article.

Practical exercise: map a topic you know well

Pick a subject you could teach, such as tea brewing, cricket bat care or home composting. In a spreadsheet, list at least twenty entities and forty queries, label each query's intent, then group them into pages under one pillar and three to five subtopics. Add a "Links to" column for every row.

You are done when every query sits in exactly one planned page, no two pages share the same main query, every page has a parent, and you have marked the first five pages to publish with a reason for each. Planning maps like this is part of SkillNewton's advanced SEO course online.

Common mistakes

• Treating a long keyword list as a topical map without grouping queries into pages or defining a hierarchy.
• Planning a separate page for every keyword variant, which produces near-duplicate pages that compete with each other.
• Ignoring intent, such as planning an informational article for a query where results show product listings.
• Building the map once and never updating it as new questions, products and competitors appear.
• Leaving the linking plan out of the map, so pages go live without connections to their parent and siblings.
